Does a dirty Data Center contribute to heat stress on server equipment?

Key Takeaways
Dust buildup on circuit boards blocks cooling airflow, raising heat and cutting server lifespan in half. Learn how SET3 helps protect your equipment from failure.

Circuit BoardThe answer is absolutely yes! Dirt and dust is deposited over boards from the incoming cooling air and is deposited like a blanket over the boards. This dirt and dust can clog air passages under chips blocking vital cooling passages. This makes cooling the servers much more difficult and if this is already a hotspot or trouble area, then it further amplifies the heat load. The Uptime Institute states that for every 10 degree raise in temperature above recommended limits the MTBF (Mean time between failures) will be reduced by 50%.
